I'd like to discuss and ask few questions on light-sound relation in art.
I already asked some of them here, but this section seems more open and free for discussion.
So, as you may know, sound and light are waves, and tone of sound comes from wave frequency. So if we take light as waves and compare it's frequency to sound, there is about one octave of waves that human percepts with eyes.
Colors inside Fletcher's palette are white piano keys, and outside are black piano keys.
The author says it's wrong to bind notes to particular colors, but ok to use colors in octave correlation.
In the following source green is marked as "C" note
Can we rotate palette and make a red color as "G" major, or forget about green mark and count it as "C"? (sorry if wrong I'm not musician)
Is it right to use rotated palette with not red as major? Does non-spectral magenta, black, gray and white require any special care?
Should we use palette as wheel or just one octave?
How do we get white light, is it interference of multiple waves ?
And if there are musicians around here, please share what you know of possibilities inside one octave.
